## Features 

Interface Module for use with a primary safety device 

The SR-IM-9A and SR-IM-11A Interface Module provides isolated safety output contacts for a primary safety device (for example, a safety light screen or safety module) with solid-state or hard contact outputs and external device monitoring (EDM) capability. 

- Normally closed outputs for connection to the primary safety device’s monitoring input. 

- • 24 V DC operation 

- 22.5 mm (0.9 inch) DIN-rail-mountable housing 

- Fixed-position push-in spring clamp terminals 

## Models 

Model Features SR-IM-9A Three normally open 6 amp redundant-output channels. SR-IM-11A Two normally open redundant-output channels and one normally closed non-safety auxiliary output channel, all rated at 6 amps. 

## Overview 

The SR-IM-9A and SR-IM-11A Interface Module operates on 24 V DC inputs and provides isolated redundant output channels for interfacing DC safety controls (such as safety light screens or other safety modules) to safety circuits. The SRIM Interface Module can also be used to switch low power capacity of safety controls with low current output rating (see wiring diagrams and the output configuration specifications). 

The outputs of the SR-IM Interface Module will follow the action of the safety outputs from the primary safety device which control it, within a 20 millisecond switching delay time. The SR-IM Interface Module’s normally open outputs each are rated for up to 250 V AC/DC at up to 6 amps. (See "SR-IM Specifications" on page 15 for derate curves.) 

The SR-IM Interface Module offers a series connection of normally closed contacts (labeled Y1-Y2 and Y3-Y4) for monitoring by the external device monitoring (EDM) function of the primary safety device. These forced-guided (mechanically-linked) contacts allow the safety device to detect failures of the Interface Module, and at a minimum, must be monitored in applications requiring Control Reliability per OSHA/ANSI or Category 3 or 4 per ISO13849-1. 

## WARNING: 

- Not a stand-alone safeguarding device 

- Failure to properly safeguard hazards according to a risk assessment, local regulations, and applicable standards might lead to serious injury or death. 

- This Banner Engineering Corp. device is considered complementary equipment that is used to augment safeguarding that limits or eliminates an individual's exposure to a hazard without action by the individual or others.

Chapter Contents 

## Chapter 2 

## Primary Safety Device Requirements 

SR-IM-9A and SR-IM-11A Interface Module are driven by one or two safety output channels of a primary safety device. For higher risk applications, the design of the primary safety device must meet OSHA/ANSI control reliability requirements (U.S. applications) or ISO/IEC/EN Category 3 or 4, Performance Level d or e. The appropriate safety circuit integrity can be determined via a risk assessment (e.g. ANSI B11.0, ISO 12100) and as described by ANSI B11.19, ISO 13849-1 or other relevant standards. The SR-IM Interface Module must be used only with primary safety devices that have External Device Monitoring capability (see wiring figures and the Warning Interfacing MPCEs). 

## At a minimum, each output channel of the primary safety device must: 

- Include one normally open forced-guided (mechanically linked) contact, or 

- • Include one solid-state 24 V DC sourcing safety output (OSSD), and • Be self-monitored to result in a safe (OFF) condition in the event of a failure, and • Be capable of switching 50 mA at 24 V DC ± 15%. 

NOTE: As OSSD solid-state outputs on primary safety devices very often are pulsed, it is possible that the relay coils will produce an audible buzzing. This relay buzzing does not affect the function of the Interface Module, as long as the pulse width is below 500 μs (microseconds) and the duty cycle (t1/ t2) is greater than 500. 

Final Switching Device (FSD): The component of the machine’s safety-related control system that interrupts the circuit to the machine primary control element (MPCE) when the output signal switching device (OSSD) goes to the OFF-state. 

Output Signal Switching Device (OSSD): The component of the electro-sensitive protective equipment (ESPE) connected to the control system of the machine which, when the sensing device is actuated during normal operation, responds by going to the OFF-state. 

## Requirements for pulsed output signals from a primary safety device 

t1 > 500 t2 t  1 +24 V DC 0 V  DC t 2 (500 µs max.) 

## WARNING: Not for use as a safety monitoring module 

1. DO NOT connect E-stop switches, 2-hand control actuators/switches, safety interlock switches, or similar devices directly to this Interface Module. 

2. ALWAYS connect terminals Y1-Y2 and Y3-Y4 of this Interface Module to the monitoring input of the primary safety device that controls it. 

This SR-IM Interface Module does not have the circuitry required to perform a self-check. A single fault inside the unit or in external devices (like switches or emergency stop buttons) can go undetected and create an unsafe condition. Failure to properly connect this Interface Module to a primary safety device with a monitoring function could result in serious injury or death.

## Chapter 3 

## Mechanical Installation 

It is the user’s responsibility to install the SR-IM Interface Module in an enclosure with NEMA 3 (IEC IP54) rating, or better. The SR-IM Interface Module mounts directly to standard 35 mm DIN rail. 

Heat Dissipation Considerations: For reliable operation, ensure that the operating specifications are not exceeded. The enclosure must provide adequate heat dissipation, so that the air closely surrounding the SR-IM Interface Module does not exceed the maximum operating temperature stated in the specifications and the derated Maximum Ambient Temperature, as a function of total contact current (see "SR-IM Specifications" on page 15). Methods to reduce heat build-up include venting, forced airflow (for example, exhaust fans), adequate enclosure exterior surface area, and spacing between modules and other sources of heat.

## Chapter 4 Electrical Installation 

## WARNING: 

- Risk of electric shock 

- • Use extreme caution to avoid electrical shock. Serious injury or death could result. • Always disconnect power from the safety system (for example, device, module, interfacing, etc.), guarded machine, and/or the machine being controlled before making any connections or replacing any component. Lockout/tagout procedures might be required. Refer to OSHA 29CFR1910.147, ANSI Z244-1, or the applicable standard for controlling hazardous energy. 

- Make no more connections to the device or system than are described in this manual. Electrical installation and wiring must be made by a Qualified Person[(1)] and must comply with the applicable electrical standards and wiring codes, such as the NEC (National Electrical Code), NFPA 79, or IEC 60204-1, and all applicable local standards and codes. 

## WARNING: 

- Determine the safety category 

- The design and installation of the safety devices and the means of interfacing of those devices could greatly affect the level of safety circuit integrity. 

- Perform a risk assessment to determine the appropriate safety circuit integrity level or safety category, as described by ISO 13849-1, to ensure that the expected risk reduction is achieved and that all applicable regulations and standards are met. 

CAUTION: Proper fusing or current limiting is required to protect the primary safety device with relay outputs in the event of a short circuit between wires leading to terminals S1/S2 and S3/S4. See Required Overcurrent Protection in the Specifications. 

It is not possible to give exact wiring instructions for an SR-IM Interface Module that interfaces to a multitude of machine control configurations. The following guidelines are general in nature. 

The SR-IM Interface Module has no delay function. Its output relay contacts open within 20 milliseconds after a safety input opens. This classifies the SR-IM Interface Module as functional stop "Category 0" control, as defined by ANSI NFPA 79 and IEC/EN 60204-1. 

The inputs can be connected to (that meet the requirements for primary safety device above): 

- A +24 V DC solid-state (PNP) outputs in single-channel or dual-channel wiring configuration, or 

- • A +24 V/0 V DC source that is switched by hard/relay contacts in single-channel or dual-channel wiring configuration. 

The dual-channel wiring configuration allows the primary safety device to detect certain failures and faults, such as short circuits, that could result in a loss of the safety function. Two-channel control should be used whenever unsafe failure of the control wires cannot be eliminated. The first circuit shown below can meet ISO 13849-1 Category 2, 3, or 4 requirements, depending on the safety rating and the installation of the primary safety device. 

The outputs of the primary safety device must, at minimum, comply with the requirements described. These outputs must be monitored for failure by the primary safety device. In addition, a single output failure cannot prevent normal stopping action, and a successive cycle cannot be initiated until the failure has been corrected. 

> (1) A person who, by possession of a recognized degree or certificate of professional training, or who, by extensive knowledge, training and experience, has successfully demonstrated the ability to solve problems relating to the subject matter and work.

These wiring diagrams are labeled ..IM..9A. The wiring for model ..IM..11A is similar, but not identical because of the different contact arrangement. 

The single-channel input wiring configuration can not detect short circuits to secondary sources of +24 V dc or detect the loss of the switching function of the primary safety device (i.e., it is not redundant) and thus this circuit typically can meet only ISO 13849-1 Category 2. 

It is recommended that in all circumstances the installation of the SR-IM Interface Module and its associated primary safety device are installed to eliminate or minimize the possibility of failures and faults that could result in the loss of the safety function(s). Methods to eliminate or minimize the possibility of these failures include, but are not limited to: 

- Physically separating interconnecting control wires from each other and from secondary sources of power. 

- • Routing interconnecting control wires in separate conduit, runs, or channels. • Locating all elements (modules, switches, and devices under control) within one control panel, adjacent to each other, and directly connected with short wires. 

- Properly installing multi-conductor cabling and multiple wires through strain-relief fittings. (Overtightening of a strainrelief can cause short circuits at that point.) 

- Periodically checking the functional integrity / safety function and training operators, maintenance personnel, and others associated with the operation of the machine to recognize and immediately correct such failures. 

If you have any questions about your intended use, please contact a Banner Engineering applications engineer at the numbers listed in "Repairs" on page 18. 

## Connection to the Machine to be Controlled

Interface Module, which stops the machinery being controlled by immediately removing electrical power from the machine and (when necessary) by applying braking to dangerous motion.

## External Device Monitoring 

To satisfy the requirements of Control Reliability (OSHA and ANSI), Category 3 and 4 of ISO 13849-1, the Primary Safety Device must have the ability to monitor the Interface Module feedback contacts Y1-Y2 and Y3-Y4 using the External Device Monitoring function. In addition, the Machine Primary Control Elements (MPCEs) must each offer a normally closed, forcedguided (mechanically linked) monitor contact. Connect one normally closed monitor contact from each Machine Primary Control Element as shown in the appropriate hookup drawing (on previous pages). 

In operation, if one of the switching contacts of the Interface Module or either MPCE fails in the energized condition, the associated monitor contact will remain open and the Primary Safety Device will lockout (fault) with an EDM error. Therefore, it will not be possible to reset the Primary Safety Device. If no MPCE-monitor contacts are monitored, it is the user's responsibility to ensure that any single failure will not result in a hazardous condition and will prevent a successive machine cycle. 

## Overvoltage Category II and III Installations (EN 50178 and IEC 60664-1) 

The SR-IM Interface Module is rated for Overvoltage Category III when voltages of 1 V to 150 V AC/DC are applied to the output relay contacts. It is rated for Overvoltage Category II when voltages of 151 V to 250 V AC/DC are applied to the output relay contacts and no additional precautions are taken to attenuate possible overvoltage situations in the supply voltage. The SR-IM Interface Module can be used in an Overvoltage Category III environment (with voltages of 151 V to 250 V AC/DC) if care is taken either to reduce the level of electrical disturbances seen by the SR-IM Interface Module to Overvoltage Category II levels by installing surge suppressor devices (for example, arc suppressors), or to install extra external insulation in order to isolate both the SR-IM Interface Module and the user from the higher voltage levels of a Category III environment. 

For Overvoltage Category III installations with applied voltages from 151 V to 250 V AC/DC applied to the output contact(s): the SR-IM Interface Module may be used under the conditions of a higher overvoltage category where appropriate overvoltage reduction is provided. Appropriate methods include: 

- An overvoltage protective device 

- A transformer with isolated windings 

- A distribution system with multiple branch circuits (capable of diverting energy of surges) 

- A capacitance capable of absorbing energy of surges 

- A resistance or similar damping device capable of dissipating the energy of surges 

When switching inductive AC loads, it is good practice to protect the SR-IM Interface Module outputs by installing appropriately-sized arc suppressors. However, if arc suppressors are used, they must be installed across the load being switched (for example, across the coils of external safety relays), and never across the SR-IM Interface Module’s output contacts.

SR-IM-9A and SR-IM-11A Interface Module Product Manual 

Electrical Installation 

## Auxiliary Monitor Contact (Model ..11A Only) 

The action of the auxiliary monitor contact, terminals 31-32, inversely "follows" the action of the safety outputs. The 31-32 auxiliary monitor contact is to be used only for control functions that are NOT safety-related. A typical use is to communicate the status of the SR-IM Interface Module output to a programmable logic controller (PLC). 

Many types of mechanisms are used to arrest dangerous machine motion. Examples include mechanical braking systems, clutch mechanisms, and combinations of brakes and clutches. Additionally, control of the arresting scheme may be hydraulic or pneumatic. As a result, an MPCE may be one of several control types, including a wide variety of contactors and electromechanical valves. If your machine documentation leaves any doubt about the proper connection points for the SR-IM Interface Module output contacts, do not make any connections. Contact the machine builder for clarification regarding connection to the MPCEs. 

Two-Channel Control: Two-channel control allows the Primary Safety Device to detect an unsafe failure of the control wires. Two-channel control should be used whenever unsafe failure of the control wires cannot be eliminated. 

The outputs of the primary safety device must at minimum, comply with the requirements described on page 5. These outputs must be monitored for failure by the primary safety device. In addition, a single output failure cannot prevent normal stopping action, and a successive cycle cannot be initiated until the failure has been corrected. 

NOTE: NOTICE regarding MPCEs To achieve control reliability, two Machine Primary Control Elements (MPCEs) are required to control each machine hazard. Each MPCE must be capable of immediately stopping the dangerous machine motion, irrespective of the state of the other. Some machines offer only one primary control element. For such machines, it is necessary to duplicate the circuit of the single MPCE to add a second MPCE. 

MPCEs must offer at least one forced-guided auxiliary contact which is wired to the monitoring contact feedback input of the primary safety device (see hookup diagrams). 

## WARNING: Interfacing MPCEs. 

NEVER wire any intermediate device(s) (e.g., PLC, PES, PC), between the SR-IM Interface Module outputs and the Machine Primary Control Elements (MPCE1 to MPCE3) it switches, in such a manner that in the event of a failure there is the loss of the safety stop command, OR in such a manner that the safety function can be suspended, overridden, or defeated, unless accomplished with the same or greater degree of safety. Whenever forced-guided, mechanically linked relays are added as intermediate switching devices, a normally closed forced-guided monitor contact from each relay must be added to the series feedback loop between Interface Module terminals Y1, Y2, Y3, and Y4.

## Mounting 

Mounts to standard 35 mm DIN-rail track. The Interface Module must be installed inside an enclosure rated NEMA 3 (IEC IP54), or better. 

## Application Notes 

## Outputs Response Time 

20 milliseconds maximum 

## Mechanical life 

20,000,000 operations 

## Electrical life 

150,000 cycles at 1,500 VA; 1,000,000 cycles at 450 VA; 2,000,000 cycles at 250 VA; 5,000,000 cycles at 125 VA 

There are no adjustments and no user-serviceable parts. 

Push-in Spring Clamp Terminals—Important: Clamp terminals are designed for 1 wire only. If more than 1 wire is connected to a terminal, a wire could loosen or become completely disconnected from the terminal, causing a short. 

Wire size: 24 to 16 AWG, 0.2 to 2.08 mm[2] Wire strip length: 8 to 9 mm 

NOTE: Transient suppression is recommended when switching inductive loads. Install suppressors across load. Never install suppressors across output contacts (see Arc Suppressors Warning). 

## Outputs 

SR-IM-9A: 3 normally open output channels 

SR-IM-11A: 2 normally open output channels and 1 normally closed auxiliary output channel 

Each normally open output channel is a series connection of contacts from two forced-guided (mechanically linked) relays, K1-K2. The normally closed contact 31-32 with the SR-IM-11A model is a parallel connection of contacts from K1-K2. 

## Low Current Rating 

The contacts allow the switching of low current/low voltage. In these low-power applications, multiple contacts can also be switched in series (e.g., “dry switching”). For low-power switching applications, maintain the switching voltage and current within the following value ranges.
